Not a big fan of psychological/twisted shit bc it does it's job and makes me feel bad, but I read this once and I felt so uncomfy. (It's Harada so you may have read it tho, if not, he's got a lot of fucked up shit)
Im interested in all sorts of manga but rn im looking for some twisted and psychological manga. if anyone can give any recommendations i will be very appreciative (〜 ̄△ ̄)〜
